This sounds to me like motor damage due to either too high rpm or more likely, high current, the arcing is a sign of comm and or coil damage.
With a DC motor, you do not get the sense of overheat until too late due to all the heat being produced by the rotor, this takes time before the heat is radiated to the stator.
When the rotor overheats, it can throw the solder on the coil/comm connections.
